Monkeybar injuries: complications of play

Clinical Review: Prepubertal Bleeding

BACKGROUND

Prepubertal bleeding is a common presentation in the pediatric office and can be distressing for patients and families. A comprehensive approach to diagnosis and management allows clinicians to identify patients at risk for worrisome pathology and arrange timely care.

OBJECTIVE

We aimed to review the key features of clinical history, physical exam, and diagnostic workup of a child presenting with prepubertal bleeding. We reviewed potential pathologies requiring urgent investigations and management, such as precocious puberty and malignancy, as well as more common etiologies, including foreign bodies and vulvovaginitis.

CONCLUSION

Clinicians should approach each patient with the goal of excluding diagnoses that require urgent interventions. A thoughtful clinical history and physical exam can inform appropriate investigations to optimize patient care.

Supracondylar humerus fractures in children caused by monkey bar-related injuries: a comparative study

We evaluated the functional and radiological outcomes of surgically treated supracondylar humerus fractures based on injury mechanisms, as well as the therapeutic and prognostic aspects of monkey bar-related injuries, in this study. Between December 2014 and December 2018, pediatric patients who had undergone surgical treatment for supracondylar humerus fractures were analyzed retrospectively. According to the mechanism of injury, patients were divided into two groups: monkey bar-related injuries and other injuries. Patients were evaluated functionally using the Mayo elbow performance score, while radiographically using the anterior humeral line, humero-capitellar angle, and Baumann angle. This study enrolled a total of 50 patients, 27 females and 23 males. Each patient was followed for a minimum of 24 months. There were no significant differences in age, sex or complications between the groups. The Mayo elbow performance score and fracture types were shown to be significantly associated with injury mechanisms ( P = 0.017, P < 0.001). Additionally, a significant correlation between the necessity for open reduction and the mechanism of injury was found ( P = 0.038). There were no significant differences in radiological evaluation between the groups. Supracondylar humerus fractures caused by falling from the monkey bar were more severe in children than supracondylar humerus fractures caused by other mechanisms of injury, and surgical treatment outcomes were worse for supracondylar humerus fractures caused by falling from the monkey bar.

COVID-19 pandemic restrictions unmasks dangers of frequent injury mechanisms for common surgically treated pediatric fractures

PURPOSE

This study examined the volume and characteristics of common surgically treated fractures in children during the COVID-19 pandemic. The worldwide spread of COVID-19 affected the society in numerous ways. Social distancing led to changes in the types of activities performed by individuals, including children. Physicians saw a shift in orthopedic trauma volume and distribution. We predicted that with the change in activities children participated in, the number or type of injuries sustained would change as well.

METHODS

A retrospective review was performed of children who sustained a surgically treated fracture of the forearm, supracondylar humerus, femur, or any open fracture during the COVID-19 pandemic compared to the previous 2 years (pre-pandemic). Patient demographics, insurance status, and mechanism of injury were recorded. Statistical analysis was performed.

RESULTS

Review of the medical records identified 791 children. The number of fractures decreased from an average of 295 per year pre-pandemic to 201 during the pandemic (p = 0.09). During the pandemic, there was a decrease in injuries resulting from a fall from the monkey bars for supracondylar humerus (21.2% to 8.2%, p < 0.01) and for forearm fractures (15.5% to 4.3%, p = 0.04). In contrast, the frequencies of falls from a skateboard, hoverboard, scooter, or bicycle and falls from household furniture increased during the pandemic.

CONCLUSION

The observed decrease in monkey bar-related injuries provides further evidence as to the dangers of this piece of playground equipment in contributing to upper-extremity fractures in children.

Orthopedic Injuries Associated with Hoverboard Use in Children: A Multi-center Analysis

BACKGROUND

Since its release in 2015, the hoverboard has been associated with injuries in children and adolescents. However, its public health implications have yet to be explored in the orthopedic literature across multiple centers.

PURPOSE/QUESTIONS

We sought to assess the nature of orthopedic injuries and the use of clinical resources related to the hoverboard at four high-volume, regional pediatric hospitals.

METHODS

Departmental databases of emergency department (ED) consultations and urgent orthopedic clinic (UC) visits were queried for hoverboard injuries. A retrospective medical record review was performed for patients presenting over a 3-month period at four institutions. Data on demographics, injuries, clinical course, and resource use were analyzed. The frequency of hoverboard-related consultations was compared to those for monkey bar-related injuries at the primary study institution.

RESULTS

Eighty-nine patients with orthopedic hoverboard injuries presented to the ED and/or UC in the study period. Hoverboard injuries represented 2.2% of orthopedic ED consultations at the primary institution, compared to 1.5% for monkey bar injuries. Sixty-nine out of 89 (77.5%) total injuries involved the upper extremity, including 47 (52.8%) distal radius fractures, the most common hoverboard-related diagnosis. All but one injury (97.8%) underwent radiography, and eight (9%) required surgery. No patients reported wearing protective gear at the time of their injury.

CONCLUSIONS

Hoverboards were associated with a variety of pediatric orthopedic injuries and required the use of significant resources in the ED, UC, and operating room. These data may represent a starting point for further prospective multi-center studies and public health efforts toward prevention of hoverboard injuries.

The feature assessment of the bone fractures in 1020 children and review of the literature

OBJECTIVE:

This study aims to collect data, which is a risk factor on bone fractures in children.

METHODS:

The study group consisted of 1020 children (n=282; 28% girls and n=738; 72% boys, with a mean age of 8.3 years) with a bone fracture. The age, gender, the month and the time of the day the fracture was sustained, mechanism of injury, feature of the fracture, the presence of coexisting injuries, and the method of treatment were recorded.

RESULTS:

Boys had approximately three times more fractures than girls. The fractures were found to be more prevalent in upper extremities (76.6%) and on its left side (56.0%), and the most commonly fractured bone was isolated radius (n=304; 32.1%); most frequently distal radius). The most prevalent lower-extremity fractures were to the femur (n=92; 31.7%). It was found that fractures occurred most frequently between the ages 3 and 6 (23.6%), and fractures in boys were most common among 13 to 15-year-old patients (n=216; 23.9%), whereas girls aged 3–6 years suffered the most fractures (n=103; 30.8%). The fractures were more common in spring (n=384; 31.0%) and summer (n=365; 29.5%). The time slot bone fractures occurred the most was from 12:00 pm to 5:00 pm (n=824; 66.6%). The most common reasons for fractures were outdoor falls (n=705; 57.0%), and indoor falls (n=239; 19.3%), respectively. Bone fractures co-occurred with head trauma the most (n=30; 42.3%). Fifty-nine patients (5.8%) had epiphysis fracture. 51 patients (5.0%) had open fractures. Five hundred ninety-two patients (58.0%) were given outpatient treatment.

CONCLUSION:

Child bone fractures are most frequently seen in the left upper extremity in 10–15-year-old boys, occurring as a result of outdoor falls in the afternoon in the spring and summer months. Bones located in the wrist, hand, and elbow have been found to be much more vulnerable to fractures. Many of the fractures were treated by conservative methods. Creating a safe environment for children is the most effective method of injury control. Necessary arrangements should be made for the safety of children in the environment and at home. Continuing education and legal regulations play an active role in injury control.

Methodological Challenges in Investigating Supracondylar Fractures of the Humerus From a Child's Viewpoint: Evolution of Study Protocol

Background

Outdoor play and risk-taking behaviors, including play at heights, are important to children’s physical, social, and cognitive development. These aspects of play are important to consider when informing prevention policies for serious injuries that commonly occur on play structures. Supracondylar fractures of the humerus (SCH) are the most common type of elbow fractures that result from falls on an outstretched hand among healthy children. Despite being one of the leading causes of admission to the hospital and surgical intervention, the details surrounding the cause of these injuries are often not recorded. Previous research has correlated decreased overall playground safety with higher rates of SCH fractures. Play structure height and the type of undersurface have been identified as potential risk factors for severe injuries, including SCH fractures, in part due to low compliance with safety standards. This paper explores the challenges we encountered designing the study and the resulting insights and methodological modifications we made.

Objective

The aim of this paper is to discuss the challenges related specifically to clinical research in pediatrics and strategies developed to conduct a study that prioritizes the engagement and perspective of children and their families.

Methods

To explore the link between the severity of SCH fractures and children’s behavioral, environmental, and mechanistic factors, we conducted a mixed-methods study.

Results

During phase 1 (the original methodology) from April 2017 to July 2018, there were 58 eligible study participants and 17 were recruited. For phase 2 (the revised methodology) between October 2018 and October 2019, there were 116 eligible participants and 47 were recruited.

Conclusions

The changes in methodology made following the first phase of data collection were effective in our ability to recruit participants. By identifying and addressing challenges pertaining to recruitment and resource limitations, we were able to collect data in a concise manner while not compromising the quality of the data and make for an easily adoptable methodology for other sites interested in participating in the study. We hope that future studies that plan to employ a similar methodology can gain insight through the methodological challenges we have encountered and the way we adapted the methodology to build a more pragmatic approach.

Playground equipment-related extremity fractures in children presenting to US emergency departments, 2006-2016

Background

Despite updated playground equipment and improved industry standards, playgrounds remain a common source of childhood injury. Fractures account for 35% of all playground injuries presenting to emergency departments (EDs). We aimed to examine the time trends and epidemiologic patterns of playground equipment-related extremity fractures in children in the United States.

Methods

We analyzed data from the National Electronic Injury Surveillance System. Children ≤14 years presenting to US emergency departments from 2006 to 2016 with playground equipment-related injuries were included. We used weighted complex survey analysis to describe the epidemiologic patterns and severity of playground equipment-related extremity fractures and Joinpoint linear weighted regression analysis to determine trends in extremity fractures.

Results

An annual average of 72,889 children were treated in US EDs for playground equipment-related extremity fractures, yielding a national annual incidence rate of 119.2 per 100,000 children. Playground equipment-related extremity fractures accounted for 33.9% of ED presentations and 78.7% of hospitalizations for playground equipment-related injuries. Of patients with playground equipment-related extremity fractures, 11.2% had severe fractures requiring hospitalization. The annual rate of ED visits due to playground equipment-related extremity fractures remained stable (annual rate of change = 0.74, p = 0.14) from 2006 to 2016. Adjusted for age, injuries on monkey bars or climbing gyms were associated with significantly increased odds of extremity fractures in comparison to injuries from other playground equipment (adjusted odds ratio [aOR]: 2.0; 95% CI: 1.9–2.1). Overall, 49.8% of extremity fractures and 54.7% of severe extremity fractures (i.e. those requiring hospitalization) occurred on monkey bars or climbing gyms.

Conclusions

Despite enhanced playground safety standards, national rates of playground equipment-related extremity fractures have remained stable in the US. Extremity fractures remain the most common type of playground injury presenting to EDs and most commonly occur on monkey bars and climbing gyms.

Playground-related Extremity Fractures in an Asian Setting over the Last Decade - Are We Safe?

The cost of playground-related injuries remains significant. Measures adopted to prevent such fractures or reduce their severity would translate into appreciable financial savings. Our study looks at the changes in playground-related extremity fracture epidemiology over the past decade after the implementation of latest playground standards. This is a retrospective case series approved by the local ethics board comparing the results of two descriptive studies; one conducted prior to the implementation of the Singapore Productivity and Standards Board Singapore Standards SS 457: 2007 and the other thereafter. The demographics have remained the same. The proportion of public playground injuries has fallen significantly from 89.6% to 76.3% (p < 0.05), whereas school playground injuries have risen from 5.9% to 18.0% (p < 0.05). Fractures related to monkey bars and the flying fox have shown a significant improvement, decreasing to 38.1% from 47.6% (p < 0.05) and 1% from 6.9% (p < 0.05), respectively. There has been a decrease of 33% in playground-related injuries. The total financial cost of sustaining one playground-related extremity fracture has generally increased by 50%. However, considering the 37.4% drop in surgeries, the actual overall costs to the healthcare system have essentially fallen. Safety standards have had a positive effect on playground safety in Singapore. There are now fewer and less severe playground-related extremity fractures.

Child Sexual Abuse identified in Emergency Departments Using ICD-9-CM, 2011 to 2014

BACKGROUND

Child sexual abuse (CSA) is poorly identified due to its hidden nature and difficulty surrounding disclosure. Surveillance using emergency department (ED) data may identify victims and provide information on their demographic profile.

OBJECTIVES

Study aims were to calculate the prevalence of visits assigned an explicit or suggestive medical diagnosis code (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM]) for CSA and compare the demographic profile of ED visits by coding type.

METHODS

This study examined ED data for children < 10 years of age in Connecticut from 2011 to 2014. Cases involving CSA were identified using explicit and suggestive ICD-9-CM codes and age qualifiers previously established in the literature, and compared across visit characteristics (age, race/ethnicity, sex, and primary insurance payer, and town group).

RESULTS

ICD-9-CM codes for explicit CSA were identified in 110 ED visits, or 1.7 per 10,000 total ED visits. Inclusion of ICD-9-CM codes for suggestive CSA identified an additional 630 visits (9.7 per 10,000 visits). Suggestive codes identified proportionally more visits of younger (50% vs. 38%) and male (35% vs. 22%) children, compared with the explicit code (p < 0.05).

CONCLUSIONS

This study demonstrates one method for identifying CSA cases, which has the potential to increase surveillance of victims in the ED. Results imply that explicit codes alone may overlook most cases, whereas use of suggestive codes may identify additional cases, and proportionally more young and male victims. As the health consequences of CSA are severe, innovative forms of surveillance must be explored to detect a higher number of cases and improve the clinical care of patients.

Inflatable bouncer-related injuries to children: increasing phenomenon in pediatric emergency department, 2002-2013

A sharp uptrend in emergency department (ED) visits for injuries associated with inflatable bouncers (IBs) has been observed recently. The aim of this study is to describe the epidemiology and features of injuries resulting from the use of IBs at an Italian pediatric ED. We collected data of 521 children from GIPSE (regional software for management of admission at ED) in the period of 2002-2013. The injuries were slightly more frequent in males than females (52.4 vs 47.6 %). Preschooler children were the most commonly injured (45.7 %). The occurrence of injuries increased by year (eight cases in 2002 and 90 cases in 2013), and a seasonal variability was reported (207 cases in the period of April-June). The most common body region injured was the upper extremity (52.4 %). Children with fractures were 126 times more likely to have injured the upper extremity rather than other body regions compared with patients with no fracture (p < 0.05). Humerus and radius/ulna fractures occurred most commonly in preschooler children (p < 0.05). Fractures were 43 times more likely to be hospitalized than children with no fracture (p < 0.05).

CONCLUSION

Injuries associated with IBs increased over time. Preschooler children were most injured, and this means there is insufficient adherence to existing recommendations concerning an age limit.

WHAT IS KNOWN

• Along with the skyrocketing popularity of IBs among children, the number of children presenting to ED with injuries from these plays has also been increasing at an alarming rate; • The European literature about this phenomenon is scarce and no specific legislations exist for safety of these devises in European Union (EU). What is New: • This is the first study in EU that examines trends for pediatric inflatable bouncer-related injuries at ED over an 11-year period. • Although American Academy of Pediatrics recommends restrictions of attendance to IBs under 6 years old, injuries and fractures continue to occur more frequently under this age.

The association between fracture rates and neighborhood characteristics in Washington, DC, children

BACKGROUND

Effects of neighborhood contextual features have been found for many diseases, including bone fractures in adults. Our study objective was to evaluate the association between neighborhood characteristics and pediatric bone fracture rates. We hypothesized that neighborhood indices of deprivation would be associated with higher fracture rates.

MATERIALS AND METHODS

Pediatric bone fracture cases treated at a tertiary, academic, urban pediatric emergency department between 2003 and 2006 were mapped to census block groups using geographical information systems software. Fracture rates were calculated as fractures per 1000 children in each census block. Exploratory factor analysis of socioeconomic indicators was performed using 2000 census block data. Factor scores were used to predict odds of bone fracture at the individual level while adjusting for mean age, sex composition, and race/ethnicity composition at census block level using our sample data.

RESULTS

We analyzed 3764 fracture visits in 3557 patients representing 349 distinct census blocks groups. Fracture rates among census blocks ranged from 0 to 207 per 1000 children/study period. Logistic regression modeling identified 2 factors (race/education and large families) associated with increased fracture risk. Census variables reflecting African American race, laborer/service industry employment, long-term block group residence, and lower education levels strongly loaded on the race/education factor. The large families factor indicated the children-to-families ratio within the block group. The poverty factor was not independently associated with fracture risk.

CONCLUSIONS

Thus, neighborhood characteristics are associated with risk for fractures in children. These results can help inform translational efforts to develop targeted strategies for bone fracture prevention in children.

Severity of playground-related fractures: more than just playground factors?

INTRODUCTION

Despite the establishment of playground safety standards, playground-related injuries are still a significant cause of extremity fractures in Singapore. This prospective study evaluates the dimensions and characteristics of our playgrounds, and their effect on fracture severity in an Asian population. We aim to correlate various playground risk factors with severity of the fractures and give recommendations on future safety standards. Our data also allows us to compare the demographics of patients in our study group with that collected in our earlier study in 2004.

METHODS

From June 2005 to 2006, children who presented with extremity fractures to KK Women's and Children's Hospital after a playground injury were enrolled. Their clinical data were collected prospectively. Relevant playground details were collected on-site independently by another investigator. For analysis of severity, fractures were "major" if they required reduction or operative fixation and were "minor" if they did not.

RESULTS

Supervision at time of injury, especially from the child's parents or siblings, resulted in a lower likelihood of "major" fractures (P=0.002, likelihood ratio=1.97). Conversely, supervision from grandparents or maids was found to result in a higher likelihood of "major" fractures. Increased weight of patients was directly related to severity of fractures (P=0.000), and a body mass index (BMI) of less than 19.8 kg/m resulted in lower likelihood of "major" fractures (P=0.010, likelihood ratio=2.22). Height of equipments and other playground-related factors were not linked to severity of fractures.

CONCLUSIONS

Supervision at the playground, preferably from the child's parents or siblings, and keeping a child's BMI within limits as guided by the BMI charts, may potentially reduce the occurrence of severe fractures.

Pediatric genital injury: an analysis of the National Electronic Injury Surveillance System

OBJECTIVE

To describe the characteristics of pediatric genital injuries presenting to United States emergency departments (EDs).

METHODS

A retrospective cohort study utilizing the U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System (NEISS) from 1991-2010 to evaluate pediatric genital injuries was performed.

RESULTS

Pediatric genital injuries represented 0.6% of all pediatric injuries with the incidence of injuries rising through the period studied, 1991-2010. The mean age at injury was 7.1 years old and was distributed 56.6% girls and 43.4% boys. A total of 43.3% had lacerations and 42.2% had contusions/abrasions. The majority of injuries occurred at home (65.9%), and the majority of patients (94.7%) were treated and released from the hospital. The most common consumer products associated with pediatric genital trauma were: bicycles (14.7% of all pediatric genital injuries), bathtubs (5.8%), daywear (5.6%), monkey bars (5.4%), and toilets (4.0%).

CONCLUSION

Although pediatric genital injuries represent a small proportion of overall injuries presenting to the emergency department, genital injuries continue to rise despite public health measures targeted to decrease childhood injury. Our results can be used to guide further prevention strategies for pediatric genital injury.

The effect of surface and season on playground injury rates

OBJECTIVE

To examine the effect of season on playground surface injury rates.

METHODS

Injuries were identified through student incident report forms used in school districts in Calgary (Alberta) and the surrounding area. Playground surface exposure data were estimated based on school enrollment.

RESULTS

A total of 539 injuries were reported during the 2007/2008 school year. Abrasions, bruises and inflammation were the most frequently reported injuries. The head, neck or face were most commonly injured. Injury rates per 1000 student days ranged between 0.018 (rubber crumb in spring) and 0.08 (poured-in-place and natural rock in the fall). Rubber crumb surfacing, compared with natural rock, had a significantly lower rate of injury in the spring, but no other season-surface comparisons were statistically significant.

CONCLUSIONS

Rates of injury were similar for natural rock, poured-in-place, and crushed rock in the fall and winter. There was some evidence of a lower rate of injury on rubber crumb surfaces in the spring.

Temporal variation in childhood injury from common recreational activities

BACKGROUND/PURPOSE

To investigate the month and day of the week of injury in common childhood activities using the National Electronic Injury Surveillance System database.

METHODS

All emergency department visits 2002–2006 from bicycles/tricycles, scooters, playground equipment, swimming/water activities, skiing/snowboarding, trampolines, and skating were analysed. The NEISS weighted and stratified data set was analysed using SUDAAN software. Weekday and month of injury, gender, race, anatomical location of the injury, geographical location of injury, and disposition were tabulated. Simple variation by month or weekday was analysed using cosinor analysis; combined variation for both month and weekday was analysed by topographical analysis.

RESULTS

There were an estimated 4.61 million emergency department visits for injuries from these activities in children in the United States. The average age was 9.5 years; there were 1.65 million girls (35.9%) and 2.97 boys (64.1%). Cosinor analysis demonstrated significant single peaks for month of injury for snow activities (January 27), trampolines (June 10), scooters (June 24), cycling (July 6), and water (July 12) activities. Double cosinor peaks were noted for skating (April 13 and September 12) and playground (April 22 and September 21) activities. Cosinor analyses demonstrated that the peak week days of injury were Monday for trampoline and snow activities, Saturday/Sunday for skating activities, Sunday for cycling, and Wednesday for playground equipment. There was no peak injury day for scooter or water activities. Topographical representation of paediatric injuries demonstrated that injuries from slides most frequently occurred April–May on Wednesdays and Saturdays, and those on swings April–May all days except Tuesday. Monkeybar injuries were bimodal, with the spring peak on Wednesday–Thursday in April/May and the fall peak Tuesday–Friday in September. Rollerblade injuries occurred Saturday–Sunday from March/April; rollerskates on Saturday–Sunday in January–April, and skateboards Saturday–Monday in August–October and Sundays in April.

CONCLUSIONS

These findings can be used to further guide childhood injury prevention programmes/campaigns and especially track improvements after targeted prevention programmes. Public parks and schools should check/correct the status of playground landing surfaces just before the bimodal peaks. Education campaigns reinforcing the need for bicycle helmets could be concentrated immediately before the increase in cycling activity – March on weekends and April/May for weekdays.

Association between upper extremity fractures and weight status in children

OBJECTIVES

Our objective was to determine the odds of having an increased weight status among children with upper extremity fracture (UEF) compared with 3 control groups without fractures.

METHODS

This is a secondary analysis of data from the Pediatric Risk of Admission (PRISA and PRISA II) data sets. Patients without chronic illness between the ages of 5 to 14 years were included in the following groups: (1) UEF study group, (2) upper extremity nonfracture injured control group, (3) minor-head-injured control group, and (4) noninjured probability control group. Weight for age/sex percentiles was used to evaluate weight status. The proportions of patients with weight for age/sex greater than the 50th, 85th, and 95th percentiles were determined. Logistic regression was used to generate odds ratios comparing the UEF group with each control group stratified by age.

RESULTS

This analysis included 308 patients in the 5- to 9-year age group and 207 patients in the 10- to 14-year age group. The odds of having a weight greater than the 50th percentile for age/sex were significantly increased among children with UEF aged 5 to 9 years compared with all control groups. There were no significant differences in the corresponding odds ratios for children with UEF aged 10 to 14 years compared with controls.

CONCLUSIONS

These findings may be related to differential injury mechanisms, mobility patterns, or underlying patient vulnerability to fracture based on weight status and bone qualities in prepubescent versus pubescent populations. Further investigation should explore fracture epidemiology and fracture risk in children stratified by age.

The cost of sustaining playground related extremity fractures in Singapore

PURPOSE

To study the cost of sustaining a fracture of the extremity caused by playground equipment. These costs include financial, psychological, clinical and others like loss of school days.

METHOD

This is a prospective study of 226 children seen at the Paediatric Orthopaedic Department for a1-year period starting June 2005. Once confirmed to have a playground related fracture by the Orthopaedic specialist, three sets of data are collected. First is the clinical data. Second is the playground related data. This is done on site independently by another investigator. Third is the radiological data,which is assessed independently by an Orthopaedic surgeon to ensure consistency.

RESULTS

Out of the 226 children seen, two-thirds were boys. The average age was 7.5 years. 35.8% were forearm fractures and 28.8% were supracondylar fractures with the rest being mostly fractures in the upper limb. 64.2% were treated with immobilisation only whilst 24.2% required closed manipulation and reduction. 1.2% required admission for treatment of their fractures. The average period of cast immobilisation was 34 days. The average number of consults, including that at the emergency department, was 4 with an average length of follow up of 67.2 days. Based on the above, in our institution, the average cost for outpatient treatment would be about S$680.00 (US$485.71) (US$1.00 = S$1.40; 1/1/2010) per injury. The inpatient cost for non-surgical treatment cost would be S$1000.00 and for surgical stabilisation the average cost would be S$3300.00 (US$2357.14).

CONCLUSION

Playgrounds are meant for children to play safely. Yet, there appears to be a significant number of injuries sustained. Whilst these fractures are relatively minor, requiring outpatient treatment,there are costs. Besides the financial costs, there are hidden psychological costs of loss of school days and inability to participate in sports. Finally, as with any injury, there can be long-term complications which present further clinical costs.

SIGNIFICANCE

Most studies on playground injuries tend to concentrate on the equipment and very superficially cover the clinical aspects, less so the costs. This paper looks at the clinical aspects in greater depth and emphasises that there are significant costs, beyond financial, when a child sustains a playground injury. The next thing to do is to examine what playgrounds factors significantly contribute to these injuries and remedy them when planning the construction of playgrounds.

An update on the epidemiology of pediatric fractures

Despite public health measures to prevent childhood injuries, the incidence of pediatric fractures is increasing. This fracture incidence is dependent on many demographic factors, the various contributors to bone health, and an individual's risk-taking behavior. Although traditional play activities continue to be the prevalent causes for fractures, there is an evolving array of new sport and recreation activities that carry significant fracture risk. The following review article outlines the developing epidemiology of pediatric fractures by analyzing some of the individual risk factors that influence fracture incidence as well as the variety of activities that are associated with these fractures.

Composite playground safety measure to correlate the rate of supracondylar humerus fractures with safety: an ecologic study

BACKGROUND

More than 200,000 children are injured at playgrounds in the United States each year. Our goal was to introduce a composite measure of playground safety and use this instrument to correlate the incidence of supracondylar humerus fractures with playground safety in an ecologic study design.

METHODS

We used a novel "overall-safety rating," defined as a composite of 3 previously validated instruments (National Program for Playground Safety School score, surface depth compliance, and the use zone compliance) to measure the overall safety of all playgrounds within a region. The regions were rated from most to least safe based on average playground safety as measured by this new method. The incidence of supracondylar fractures was calculated using Hasbro Children's Hospital Emergency Department data and state of Rhode Island Census data from 1998 to 2006. The incidence was then correlated with playground safety as defined by our composite measure.

RESULTS

Compared with the neighborhood deemed the safest, the least safe district had 4.7 times greater odds of supracondylar humerus fracture. Overall composite safety score of the district was linearly correlated with the injury rate observed in the population at risk (R=0.98; P=0.04).

CONCLUSIONS

Using our novel composite playground safety score, we found that the incidence of supracondylar humerus fractures was increased in districts with playgrounds with lower scores, suggesting that improvements in playground infrastructure may potentially reduce the incidence of supracondylar humerus fractures, and other injuries, in children.

Prevalence of vitamin D insufficiency in African American children with forearm fractures: a preliminary study

OBJECTIVES

Forearm fractures account for a significant proportion of childhood injuries and seem to be increasing in incidence. Poor vitamin D status increases overall fracture risk in infants with rickets and adults with osteoporosis. Children with vitamin D insufficiency (serum 25-hydroxy vitamin D level <20 ng/mL) have decreased bone mineral density (BMD) compared with children having normal vitamin D status. The relationship between vitamin D status and childhood forearm fracture has not been investigated.

METHODS

This prospective study enrolled African American children, aged 5 to 9 years, with a forearm fracture. Bone health evaluation included measurement of serum 25-hydroxy vitamin D level and BMD by dual energy x-ray absorptiometry scan. Univariable analyses were used to test the associations between fracture status and the independent variables, serum vitamin D level and BMD.

RESULTS

Vitamin D levels were available for 17 cases. The mean (+/-SD) 25-hydroxy vitamin D level was 20.1 (+/-7.3) ng/mL with a range of 10 to 38 ng/mL. The mean of this group was at the cut point for vitamin D insufficiency. Ten cases (59%) were vitamin D insufficient. Dual energy x-ray absorptiometry scan results for these patients were consistent with normal bony mineralization for age.

CONCLUSIONS

A significant proportion of African American children with fractures in our study have vitamin D insufficiency. Analysis of serum 25-hydroxy vitamin D levels and BMD in additional cases and controls will determine the significance of these findings.

CLINICAL RELEVANCE

Vitamin D insufficiency may play a previously unrecognized role in childhood fractures. Strong consideration should be given to routine vitamin D testing in African American children with forearm fractures.

Pediatric vulvovaginal disorders: a diagnostic approach and review of the literature

Vulvovaginal complaints in the prepubertal child are a common reason for referral to the health care provider. The Cochrane Library and Medline databases were searched for articles published in English from 1980 to December 2004 relating to vulvovaginal conditions in girls. The following search terms were used: vulvovaginitis, prepubertal, pediatric, lichen sclerosis, labial fusion, labial adhesion, genital ulcers, urethral prolapse, psoriasis, and straddle injuries. The objectives of this article are to review the normal vulvovaginal anatomy, describe how to perform an age-appropriate examination, and discuss common vulvovaginal disorders and their management in young girls.

Pediatric tree house-related injuries treated in emergency departments in the United States: 1990-2006

OBJECTIVES

The objective was to describe the epidemiology of tree house-related injuries in the United States among children and adolescents.

METHODS

The authors conducted a retrospective analysis using data from the National Electronic Injury Surveillance System for patients < or =19 years who were treated in an emergency department (ED) for a tree house-related injury from 1990 through 2006.

RESULTS

An estimated 47,351 patients < or =19 years of age were treated in EDs for tree house-related injuries over the 17-year study period. Fractures were the most common diagnosis (36.6%), and the upper extremities were the most commonly injured body part (38.8%). The odds of sustaining a head injury were increased for children aged <5 years. Falls were the most common injury mechanism (78.6%) and increased the odds of sustaining a fracture. Falls or jumps from a height > or =10 feet occurred in 29.3% of cases for which height of the fall/jump was recorded. Boys had significantly higher odds of falling or jumping from a height of > or =10 ft than girls, and children 10 to 19 years old also had significantly higher odds of falling or jumping from a height of > or =10 feet, compared to those 9 years old and younger. The odds of hospitalization were tripled if the patient fell or jumped from > or =10 feet and nearly tripled if the patient sustained a fracture.

CONCLUSIONS

This study examined tree house-related injuries on a national level. Tree house safety deserves special attention because of the potential for serious injury or death due to falls from great heights, as well as the absence of national or regional safety standards. The authors provide safety and prevention recommendations based on the successful standards developed for playground equipment.

Pediatric Heelys injuries

BACKGROUND

To determine the incidence and severity of injuries caused by Heelys.

METHODS

A retrospective review of all fractures presenting to an orthopaedic emergency room at a metropolitan children's hospital during a 90-day period. The type of fracture, mechanism of injury, and management were recorded for each patient. For those injuries related to the use of Heelys, further data were collected including total number of visits, cast changes, and cost. Each Heelys patient/family was contacted and answered a questionnaire detailing their use of Heelys and the events surrounding the injury.

RESULTS

A total of 953 patients with fractures were evaluated for 90 days. Sixteen patients with 17 fractures (1.68%) were identified as being related to the use of Heelys. This compares to the incidence of fractures in our sample from basketball (6.19%), bicycle (4.41%), football (4.09%), monkeybars (3.78%), skateboarding (3.25%), soccer (2.62%), baseball (2.52%), and trampoline (2.31%). The average age of each Heelys patient was 8.9 years, and 13 patients were girls. There were 16 upper extremity and 1 lower extremity fracture. No patient needed operative treatment or admission. Average number of follow-up visits was 1.6, with an average of 1.4 casts per patient. Average cost per patient was $1368. Ninety-two percent of the Heelys injuries occurred outdoors. Fifty-four percent of children were being supervised when they fell, but only 31% were wearing any safety equipment. Sixty-two percent of parents were not aware that safety equipment was recommended. All 13 parents indicated that they would not purchase another pair of Heelys, and only 23% of the children wanted to keep using Heelys after the injury.

CONCLUSIONS

The incidence of Heelys injuries (1.68%) was relatively low compared with other common childhood play activities. The fractures were mostly in the upper extremity, and no fracture required surgical intervention or admission to the hospital. Sixty-two percent of the parents were not aware that safety equipment was recommended, and only 31% of the children were wearing safety equipment.

The demographics of playground equipment injuries in children

BACKGROUND/PURPOSE

There have been many different studies of injuries owing to playground equipment but none that have looked in detail using large nationwide databases. It was the purpose of this study to investigate injuries owing to playground equipment using the National Electronic Injury Surveillance System (NEISS) database and further understand their demographics.

METHODS

Detailed NEISS injury data from 2002 through 2004 for slides, monkey bars, and swings were analyzed. Appropriate statistical analyses were performed; because of the many analyses on this large data set, P < .01 was considered statistically significant.

RESULTS

There were 22728 emergency department visits owing to playground equipment injuries recorded by NEISS between 2002 and 2004; 83.9% were owing to monkey bars, swings, and slides, and the 5 most common diagnoses were fractures (39.3%), contusions/abrasions (20.6%), lacerations (16.6%), strains/sprains (9.9%), and traumatic brain injuries (TBI) (8.5%). There were 9487 boys (54.3%) and 7995 girls (45.7%). The average age was 6.5 +/- 3.0 years. The injuries occurred at school in 38.9%; at a recreation/sporting facility, in 35.5%; and at home, in 25.6%. Most were treated and released (94.4%). Amerindian children were 2 times more likely than blacks to be admitted; compared to contusions, fractures were 9.8 times, and TBIs, 4.7 times more likely to be admitted. Injuries on monkey bars were 1.2 times more likely to be admitted than those on swings or slides. Fractures were 1.9 times more likely to occur on a monkey bar compared with swings or slides. Traumatic brain injuries were 1.4 times more likely to occur on a swing compared to slides or monkey bars.

CONCLUSION

Swings at school are the most common mechanism of injury for TBIs, and the seasonal data would suggest that increased supervision of children using swings during school hours might reduce the occurrence of TBIs. Monkey bars are the most common cause of fracture, and fracture is the most common cause of admission. Prevention strategies to reduce the number of fractures should be directed at monkey bar equipment and landing surfaces. The trend in playground equipment injury also indicates that monkey bars are problematic because the number of injuries per year per capita owing to monkey bars is stable, whereas those from swings and slides is decreasing.

Parental administration of analgesic medication in children after a limb injury

OBJECTIVE

To document parental administration of analgesic medication to children with pain from acute limb injury before coming to the emergency department (ED).

METHODS

Research assistants interviewed parents of children 0 to 18 years old who presented to the ED with acute limb injury, asking about analgesic use before arriving to the ED. Parents were also asked for personal and demographic information. Parents who did not give pharmacological analgesia were asked why they decided not to administer medications. All parents were asked if they will administer analgesia in the future.

RESULTS

A total of 72% of parents administered analgesia (pharmacological or others) to their children. Only 28% of the children received pharmacological analgesics before arriving to the ED. Child's mean age was higher for the group receiving medications, compared with those not receiving medications (99 +/- 50 vs 122 +/- 52 months, respectively; P = 0.005). The main parental concern about analgesic use was of potential masking of the clinical signs and symptoms before being seen by a physician.

CONCLUSIONS

Prehospital analgesic administration by parents is mainly nonpharmacological largely because of parental concern of interference with medical assessment or underestimating the child's pain. Parental concern of masking symptoms and parental perception of no pain in a child were significant factors in determining parental comfort level in using pharmacological analgesics.

Recognition and management of pediatric fractures by pediatric residents

BACKGROUND

Competence in basic orthopedic assessment and interpretation of radiographs is important for pediatricians because appropriate initial management of fractures can expedite therapy and minimize morbidity. However, requirements for training in orthopedics and radiology are poorly defined in pediatric residency programs.

OBJECTIVE

To assess the ability of pediatric residents to recognize and to manage appropriately pediatric fractures.

METHODS

This study involved administration of a case-based questionnaire with radiographs to volunteer categorical pediatric residents in 3 geographically diverse training programs. The diagnosis and management of 8 orthopedic complaints were evaluated. Responses were scored according to the number of features identified accurately, including the presence or absence of a fracture. Residents who were able to identify a fracture were assessed with respect to their ability to classify the fracture and to provide initial management. The study was pretested with a group of pediatric emergency medicine attending physicians, to establish the suitability of the cases.

RESULTS

Among the 3 residency sites, 102 of 190 eligible pediatric residents (53.7%) participated, yielding 95 completed questionnaires. The mean number of cases in which a resident correctly answered the question, "Is a fracture present?" and correctly identified the fractured bone (if a fracture was present) was 6.5 +/- 1.2 of 8 cases (81.6%; 95% confidence interval: 78.5-84.7%). The diagnostic accuracy of Salter-Harris classification in cases in which such fractures were present was 40.9%. The mean score of correctly identified features for the resident group was 38.5 +/- 9.4, of a possible 64 points (proportion correct: 60.1%; 95% confidence interval: 57.2-63%). There was a small but significant difference in mean correct responses between first-year residents (proportion correct: 55.4%; 95% confidence interval: 50.8- 60.3%) and third-year residents (proportion correct: 65.1%; 95% confidence interval: 60.7-69.5%). There was no association between the proportion of correct responses and whether or not residents had taken radiology or orthopedics elective courses in medical school. Overall, 43% of cases were both identified and managed correctly by the pediatric residents.

CONCLUSIONS

For residents from the participating training programs, skills in recognizing and managing pediatric fractures were suboptimal. Additional review of training requirements is necessary to identify more clearly areas of improvement for current curricula.

Policy issues and risk-benefit trade-offs of 'safer surfacing' for children's playgrounds

The case for the universal application of 'safer surfacing' in playgrounds is assessed in terms of absolute risk, cost-benefit, and qualitative factors, and found to be open to question on each front. In parallel, it is noted that members of the child welfare and play communities are increasingly of the view that playgrounds are losing their appeal for children, which in turn has its own health, safety and developmental consequences. In part, this loss of attractiveness may have linkages with the recent concern over play safety and the imposition of measures such as 'safer surfacing'. It is proposed that the drive for play safety, which has existed for some 20 years, should be succeeded by a more holistic approach which, rather than considering play safety in isolation, acknowledges the importance of all attributes of play including child safety both on and off playgrounds, potential beneficial aspects of childhood risk exposure, adventure, and play value.

On-the-field evaluation of an athlete with a head or neck injury

Head and cervical spine sports-related injuries are intimately associated. The on-field evaluation and management of the athlete with these injuries is of paramount importance to stabilize the athlete and prevent further injury. Clinicians need to be aware of the differential diagnoses and consider each possibility based on the mechanism of injury. Although recognition of head and cervical spine injuries has resulted in significant reductions of catastrophic neurological injuries, especially in the cervical spine, further advances to decrease the incidence and long-term sequelae of head and neck injuries are needed. The first step is education of the athlete and the individuals involved in the care of that athlete.

[Playground safety: an introduction to the problem]

This study aims to approach the theme of accident prevention in relation to the use of playground toys, which is little explored in national literature. It is estimated that, annually, more than 200,000 accidents with children happen in playgrounds in the United States of America. Besides discussing this problem, we present some general recommendations about safety in these places and a reflection on the need to alert and educate society about the importance of prevention.

Playground injury prevention

Playground safety recently has received increasing attention from parents and municipalities. Orthopaedic surgeons treat a large number of the more than 350,000 injuries per year sustained on the play areas of this country's school, home, and community play areas. A parent brings a child to the playground for fun, healthy exercise, and imaginative play. Unfortunately, most parents may not be aware of recommended injury prevention methods. Data from the Consumer Product Safety Commission and other epidemiologic studies document frequency, identify at-risk activities and equipment, give direction for additional research, and guide regulations. It is appropriate for the medical community to lead in this safety effort and to contribute to additional research and advocacy efforts.

Trends and patterns of playground injuries in United States children and adolescents

OBJECTIVE

To determine the prevalence, trends, and severity of injuries attributable to playground falls relative to other common unintentional mechanisms that resulted in an emergency department (ED) visit in the United States.

DESIGN AND SETTING

Data from the emergency subset of the National Hospital Ambulatory Medical Care Survey collected from 1992 to 1997 for children <20 years.

METHODS

Injury rates and 95% confidence intervals (CIs) were estimated and injury severity scores were computed.

RESULTS

There were 920551 (95% CI: 540803 to 1300299) ED visits over the 6-year study period by children and adolescents that were attributable to falls from playground equipment. The annual incidence of visits for playground injuries did not significantly decrease over the course of the study (187000 to 98000, P =.053). Injury visits for playground falls were twice as prevalent as pedestrian mechanisms, but they were less prevalent than visits for motor vehicle-- and bicycle-related injuries. A larger proportion of playground falls resulted in "moderate-to-severe" injury than did bicycle or motor vehicle injuries. Children aged 5 to 9 years had the highest number of playground falls (P =.0014). Playground falls were most likely to occur at school compared to home, public, and other locations (P =.0016).

CONCLUSIONS

Playground injury emergency visits have not significantly declined and remain a common unintentional mechanism of injury. Injury visits for playground falls were proportionally more severe than injury visits attributable to other common unintentional mechanisms. Interventions targeting schools and 5- to 9-year-old children may have the greatest impact in reducing emergency visits for playground injuries.

Traumatic brain injury research: a review of clinical studies

There is a growing volume of research on trauma brain injury (TBI) as evidenced by a recent Medline search that reported over 6000 articles published on TBI in the past 5 years.

Decreasing children's risk taking on the playground

Playground mishaps are some of the most common sources of injury and are the leading killer of children. The present study used a multiple baseline design across three classrooms (N = 379 children). With minimal teaching and rewards, children decreased and maintained decreased risky playground behaviors on slides. Floor effects on climbers prevented the demonstration of similar effects. The decreases seen in risky slide behavior are discussed within the context of preventive safety training for playground injuries.

Head and neck injuries in young athletes

Careful study of the pathophysiology and epidemiology of sports-related spine injuries brings to light many common features. The incidence increases as the sport becomes increasingly violent and aggressive. Poor conditioning and lack of knowledge of the proper techniques of the sport put the athlete at significant risk for head and spine injury. Improper helmet fit and the use of the head as an offensive weapon also are common features of injury. Although recognition of these features has resulted in a dramatic reduction in catastrophic neurological injury, the athlete remains at risk for less severe head and spine injury, and concussion remains at epidemic proportions at high school, university, and professional levels. It is hoped that careful recognition of the signs of concussion and knowledge of return-to-play criteria will prevent catastrophic complications from minor head injuries, although the long-term effects of multiple concussions on cognition may be problematic.

Mechanisms of blunt perineal injury in female pediatric patients

BACKGROUND/PURPOSE

Controversy persists regarding the causes of and the morbidity associated with blunt perineal injuries in children. The purpose of this study was to determine the most common mechanisms of blunt perineal trauma in female pediatric patients and to define the subset of patients that may benefit the most from an examination under anesthesia (EUA).

METHODS

Nearly 4,450 female pediatric patients were entered in the Pennsylvania Trauma Outcome Study database between 1993 and 1997. The mechanism and extent of perineal injury, surgical repair, and associated injuries were examined for all girls 0 to 16 years of age with a diagnosis of blunt perineal trauma.

RESULTS

A total of 358 girls experienced blunt perineal trauma. Motor vehicle crashes (MVC) accounted for the majority of injuries in all age groups. Falls and bicycle-related injuries were significantly more prevalent in children less than 9 years of age, and assaults in children 0 to 4 years. Head trauma was the most common associated injury in children less than 15 years. Children less than 10 years of age required surgical repair of their perineal injuries more frequently than their older counterparts. Perineal injuries caused by falls, assaults, or playground-related equipment were more likely to require surgical repair than those caused by other mechanisms.

CONCLUSIONS

Perineal injuries that require surgical repair occur predominantly in patients less than 10 years of age who sustain blunt perineal trauma from a variety of causes, but rarely MVC. Thus, such patients should undergo aggressive evaluation, including EUA, especially if they present with perineal bleeding, hematoma, or swelling. Furthermore, perineal injuries in children under 4 years should raise the suspicion of abuse.
